This happened about three and a half thousand years ago, in the Sinai Desert, near Mount Sinai. Such symbols exist in our world because each spiritual root is obliged to touch its material branch.
This holiday is significant in that a person receives a connection with the upper force. Otherwise, we would remain animals that exist aimlessly on Planet Earth, which is rushing somewhere in a lifeless space.
And now we can connect with the very force that created the universe, the globe, and the people on it, and that launched the entire process of evolution. We can find out what is behind this process, what are the forms of relations between us and the higher power.
Shavuot is a great holiday because we celebrate gaining connection with the Creator, which allows us to rise from this life, from its aimlessness and meaninglessness, above this animate existence. There is no holiday bigger than the giving of the Torah; everything starts with it! If it weren’t for it, our lives would be in vain.
We would remain ordinary animals born in order to live and die. The Torah gives us the opportunity to rise above our lives, comprehend a higher power, and enter eternity, perfection, another dimension that is based on bestowal, not reception.
Our world exists only within egoism, reception, and the spiritual world exists for the sake of bestowal; therefore, it is eternal and perfect. Thanks to this means, which is called the Torah, we have the opportunity to rise from the lower world to the higher one.
Therefore, we celebrate Shavuot, in which there are not many symbols: white clothes and dairy food are symbols of bestowal. Those are all the characteristics of this holiday.
According to history, the giving of the Torah occurred after the people of Israel left Egypt, that is, after fleeing from the selfish intention and crossing the Red Sea (Yam Suf), which meant breaking off from egoism and entering the Sinai Desert, the place where hatred (Sinaa) between altruistic and egoistic desires is revealed.
And then a person faces a mountain of doubts. Har (mountain) comes from Hirhurim (doubts). How many objections we have against the desire for bestowal is revealed to us and we need to work on them. Therefore, we shout: “Where is the tool that will allow us to achieve bestowal? We do not have such strength!”
Then we get a power from above called “the upper light,” “Torah,” that is, “light” (Ohr), “program,” “technique” (Ora’a). Thus, we begin to develop purposefully.
Until now we are making correction after correction in our egoism, generation after generation, until we come to the end of correction. All this is possible thanks to the hidden power of the Torah, which is called “the light that returns to the source,” the highest light of correction.
In the days of this holiday there is a special power in the world. And if we study it together, it will move us forward.
